Question

what is the percent of increase from 2.5 to 2.5? round your answer to the nearest tenth of a percent and include a percent sign (%).

Explanation:

Step1: Recall the percent increase formula

The formula for percent increase is $\text{Percent Increase} = \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \times 100\%$.

Step2: Identify the old and new values

Here, the old value is $2.5$ and the new value is also $2.5$.

Step3: Substitute into the formula

Substitute the values into the formula: $\frac{2.5 - 2.5}{2.5} \times 100\% = \frac{0}{2.5} \times 100\% = 0\%$.

Step4: Round to the nearest tenth of a percent

Since $0\%$ is already a whole number, when rounded to the nearest tenth of a percent, it remains $0.0\%$.

Answer:

$0.0\%$
